Question juridique clé
Whether the subletting rent constituted usury under Art. 157 CP
Solution extraite
The cantonal court had not established the objective market value of comparable housing, so the usury finding could not stand and had to be reconsidered.
Motifs extraits
Usury requires an obvious economic disproportion assessed objectively against usual prices for comparable properties. The lower court wrongly relied mainly on the main lease rent without first finding that it matched market rent; it also had to examine whether a furniture supplement was justified.
